NON-REFILLABLE BOTTLE. i

Specification of Letters Patent.

Patented Dec. 18, 1906.

Application filed June 25, 1906. Serial No. 323,209.

To all whom t may concern:

Be it known that we, AUGUsT G. SCHWEIZER and EDWARD J. THOMAS, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new andv tured very cheaply without the use of metal or other deleterious material in its construction.

To this end the invention consists in providing a glass plug adapted to be forced into the neck of the bottle, with an interposed yielding lining adapted to form a tight joint and to engage shoulders on the neck of the bottle to prevent the removal of the plug; and it further consists in casting the plug in like halves with a tortuous passage for the liquid formed with a plurality of valve-seats for ball-valves which are inserted therein before the halves are inserted in the bottleneck, and also in providing certain other new and useful features in the construction, arrangement, and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in Which- Figure l is a transverse vertical section of a bottle embodying the invention, and Fig. 2 a section on the line a: of Fig. 1 of the plug detached.

As shown in the drawings, l is the body of a bottle provided with an elongated straight neck 2, which at its base is formed with an inwardly-projecting annular shoulder 3 and at a distance from its upper end with an opposing shoulder 4 of lesser projection, the inner surface between said shoulders being straight and smooth and the surface above the shoulder 4, which is of a slightly less diameter, being also straight and smooth and adapted to receive the ordinary cork 5 in its outer end.

6 is a cast-glass plug made in halves and each half formedwith one-half of a tortuous tubular passage 7 for the escape of the liquid from the bottle, said passage being formed with several sharp turns or bends all in the tranverse vertical plane of the dividing-line of the plug to prevent the insertion of a wire or other instrument therethrough. Laterally-eXtending chambers 8, 9, 10, and 11 are formed at intervals along the passage to receive balls l2, which are adapted to move by gravity into the ends of the chambers opening into the passage, which ends form a part of the passage and also form seats for the balls and close the passage when the bottle is held in a certain position. The chambers 8 and 9 each extend vertically, and the passage vis so curved that it enters the lower end and opens from the side of each, and thus when the bottle is in its vertical position, as shown in Fig. l, the balls fall into their seats 13 in the lower erids of the chambers and close the passage against the admission of liquid into the bottle and the escape of the fumes or evaporation of the liquid therefrom. When the bottle is tipped to the left from its position shown in Fig. l, the ball in chamber 8 will seat itself in its seat 14, formed in the side of said chamber, and prevent the liquid from iiowing through the passage, and when tipped to the right the ball in chamber 9 will find its seat 14 and close the passage, and thus the ballsin chambers 8 and 9 serve to close the passage when the bottle is in its vertical position or when tipped to the right or left from that position, but will not do so when the bottle is tipped in a plane at right angles to theplane in which it moves when tipped to the right or left. The chambers 10 and 11 are therefore provided for the retention of balls to close the passage when the bottle is so tipped, said chambers extending laterally from the passage in an upwardly-slanting position, so that when the bottle is standing in an upright position the balls will roll by gravity into their seats I3 at the lower ends of the chambers and close the passage, and when tipped to the right from the position shown in Fig. 2 the ball in chamber 11 will remain so seated, and when tipped to the left the ball in chamber 10 will prevent the passage of the liquid. A tipping in any direction will thus cause one or more of the balls tov seat and close the passage 5 but by inverting the bottle the balls will all move to the outer ends oftheir chambers, and thus permit4 the IOO TIO

liquid to iow out freely. If an attempt y should be made to force liquid into the bottle through the passage when the bottle is so inverted, the pressure of the stream would raise the ball in chamber 8 to its seat 13, as the passage at 15 between its open end and said chamber is curved in such a manner as to direct the stream upon the side of and beneath the ball.

Inputting up the liquid the bottle is filled in the ordinary way before the plug is inserted. Two halves of the plug are then placed and cemented together with the ball-valves in their chambers and a suitable tubular sleeve 16, of rubber, cork, or other suitable yielding material, slipped over the plug and cemented or otherwise secured in place with its upper end against a shoulder 17 on the plug. The plug is then forced into the neck of the bottle, the sleeve being compressed to pass through the reduced upper end thereof above the shoulder 4, and when it has passed said shoulder expands and its upper end engages beneath said shoulder, thus preventing the removal of the plug. The'lower end of the plug and sleeve seat upon the shoulder 3, which covers the lower lend of said sleeve, thus protecting the same from tainting the liquid or being 4injured by it. The upper end of the plug fits closely within the bottle-neck above the sleeve, so that said sleeve cannot be reached and loosened from the plug to permit the removal thereof.

Having thus fully described the invention, what we claim is- The combination with a bottle having a straight neck, of an inwardly-projecting shoulder at the base of the neck and a similar shoulder near they upper end of said neck, a plug formed in halves with a tortuous passage in the plane of the division and vertically-extending chambers into the bottoms of which the passage opens and from the sides of which it extends, a valve-seat being formed in the bottom and in the side of each chamber and the passage leading from the side of one chamber being curved downwardly to direct liquid into the upper end of said chamber, and laterally and upwardly extending chambers being arranged in a plane at right angles to the plane of division and opening into said passage at each side thereof, balls in said chambers, a shoulder on the plug near its upper end forming an end adapted to fit within the bottle-neck, and a yielding sleeve on the plug adapted to be engaged between the shoulcers on the bottleneck.

In testimony whereof we aflix our signae tures in presence of two witnesses.
